A comparative evaluation of Tauleed-e-harārat and thermogenesis: An interdisciplinary perspective

Abstract

The generation and regulation of heat within the human body have been central to both classical Unani medicine and modern physiological science. In Unani literature, Tauleed-e-Harārat (production of heat) is described as an intrinsic process essential for the maintenance of life, governed by the innate heat (Harārat-e-gharīziya) and influenced by temperament (Mizāj), humours (Akhlāṭ), and vital organs (A‘ḍā’ Ra’īsā). Unani scholars such as Ibn Sīnā, Rāzī, Majūsī, and Jurjānī described in great detail how heat is produced, distributed, and preserved in the human body. Modern physiology, on the other hand, explains this phenomenon under the concept of thermogenesis, involving biochemical and metabolic pathways such as mitochondrial oxidative phosphorylation and hormonal regulation through thyroid hormones and catecholamines. This comparative study aims to explore conceptual parallels and scientific correlations between Tauleed-e-Harārat and thermogenesis. The study reveals that both systems recognize heat as a vital factor in sustaining life and regulating metabolic processes, though their explanatory frameworks differ. While Unani theory emphasizes qualitative and holistic aspects of heat, modern science defines it quantitatively through energy metabolism. The study concludes that integrating Unani and modern perspectives can enrich the understanding of human thermoregulation and support interdisciplinary approaches to health and disease management.
